对于超纯水（UPW）生产中的水的去矿化（在25℃下> 18MOhm * cm）。Lewatit UltraPure 1296MD是即用型混合床，其包含凝胶型强酸性阳离子交换剂树脂（SAC，Lewatit UltraPure 1216 MD）和凝胶型强碱性阴离子交换树脂（SBA，I型，UltraPure 1243 MD），单独地具有基于苯乙烯 - 乙烯基化合物的单分散珠尺寸分布（均匀颗粒）二乙烯基苯共聚物，用于生产超纯水的抛光系统。单分散珠（均匀系数：好大1.1）具有化学和渗透高度稳定性。优化的动力学导致增加的操作能力，并且与离子交换相比，非常低的细粒含量也导致低压降带有异分散珠粒大小分布的nge树脂.Lewatit®UltraPure 1296 MD相应地调整到各组分的总容量，其当量比为1：1。 SAC较小的珠粒尺寸有助于改善混合性能.Lewatit®UltraPure 1296 MD经过高度再生和特殊清洁，符合半导体行业的规格要求。从Lewatit®UltraPure 1296 MD中将有机物浸出到处理过的水中的浓度降低到低于1.0 ppb的水平，并且其电阻率达到高于18 MOhm * cm的水平。

For the demineralization of water in the production of ultra pure water (UPW) (> 18 MOhm*cm at 25°C).

Lewatit® UltraPure 1296 MD is a ready-to-use mixed bed comprising a gel type strongly acidic cation exchange resin (SAC, Lewatit® UltraPure 1216 MD), and a gel type, strongly basic anion exchange resin (SBA, type I, Lewatit® UltraPure 1243 MD), individually with a monodispersed bead size distribution (uniform particles) based an a styrene-divinylbenzene copolymer for the use in polishing systems for the production of ultra pure water.

The monodisperse beads (uniformity coefficient: max. 1.1) are chemically and osmotically highly stable. The optimized kinetics lead to an increased operating capacity, and the very low content of fines also results in a low pressure drop compared to ion exchange resins with heterodisperse bead size distribution.

Lewatit® UltraPure 1296 MD is correspondingly adjusted to the total capacity of the individual components to an equivalent ratio of 1:1. The smaller bead size of the SAC contributes to better mixing properties.

Lewatit® UltraPure 1296 MD is highly regenerated and specially cleaned for meeting the specifications of the semiconductor industry. Leaching of organics from Lewatit® UltraPure 1296 MD into the treated water is reduced to a level less than 1.0 ppb, and its resistivity achieves a level higher than 18 MOhm*cm.
